Application filed July 21, 1910. Serial No. 573,101.

To all whom it may concern: Be it known that I, Bnnnnrr \Voooonor Haniioivn, a citizen of the United States, residing at Richmond, in the county of Alameda and State of California, have invented certain new and useful Improvements in Vehicle-Vheels, of'which the following a specification.

This invention relates to spring wheels, and. the principal object ofthe same is to provide a novel resilient connection between the rim and the felly of the wheel by means of. which the shock and'jars'incidental to travel are absorbed.

In carrying out the objects of the invention generally stated above it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in details and structural arrangements, one preferred and practical embodiment of which is shown in the accompanying drawings, wherein Figure 1 is a view in side elevation of a wheel constructed. in accordance with this invention. Fig. 2 is an enlarged transverse sectional view taken on the line AA, Fig. 1. Fig. 3 is a fragmentary longitudinal sectional view taken on the lines B-GD, Fig. 2. Fig. 4 is a top plan View of one of the lugs to which the connecting springs are fastened. Fig. 5 is a view in side elevation of a rotatable sleeve used in connection with the lug shown in Fig. 4. Fig. 6 is an endview of one of the springs that are interposed between the folly plate and rim showing an end roller carried thereby.

Referring to the accompanying drawings by numerals, it will be seen that the improved wheel comprises a hub 1 from which the spokes 2 radiate, said spokes carrying the usual felly 3. A plate 4 is carried by the periphery of felly 3, said platev being provided with an outwardly projecting right-angular guard extension 5 at one side. The other side of saiclplate carries a similar guard 6 the angular base 7 of which is riveted or otherwise rigidly fastened to the underside of plate 4.

Semi-elliptical laminated springs 8 are arranged at regular intervals on the outer surface of plate 4, one end of said springs being bolted or otherwise rigidly but detachably fastened to said late, and the free ends of said springs aving one of their leaves equipped with integral ears 9 in which the shafts 10 are mounted. Shafts 10 are equipped with rollers 11 which travel on plate 4 to reduce friction. Conical spiral springs 12 are also carried by plate 4, said springs being interposed between said plate and the arched portions of springs 8 and obviously oppose compression thereof.

Side plates 13 are slidably clamped to the side guards 5 and 6 of plate 4 by the bolts 14. Said plates are provided with cavities 15 in which felt or other lubricant soaked absorbent material is'placed to prevent friction between said plates 13 and the guards 5 and 6. A rim 16 is carried by plates 13. said rim having a resilient tirc 17 fastened thereto by the wires 18. Said rim rests on the arched portions of the laminated springs 8.

Rim 16 and plate 4 are provided with a plurality of lugs 19, said lugs being arranged in pairs the members of which are diagonally disposed, one memberof each pair being carried by the rim and the other member :arried by the plate 4. Each lug is provided with a pair of cars 20 which support a shaft 21 upon which asleeve 22 is rotatably mounted. Spiral springs 23 are employed for connecting the pairs of lugs, saidsprings having their ends fastened to the pulleys 22, and obviously being arranged in crossing relation.

In operation it will be seen that the springs 8 oppose the sliding movement of the rim relative to the folly, and that the springs 12 oppose the compression of springs 8. The spring connections 23 between the rim and plate 4 oppose a rotary movement of the rim relative to the felly.

Springs 8 and 12 are placed in position under compression and are therefore constantly exerting a pressure in opposition to a movement that would cause rim 1G to approach plate 4, and springs are. placed in position under tension so that they tend to prevent a relative rotation of said rim and plate.

What I claim as my invention isr-- A wheel comprising a folly plate, a rim,

clamping plates carried by said rim and 1 means carried by the free ends of said semi- & 1,062,5 35
